Setup Yocto environment

• WorkDir

mkdir compulab-bsp && cd compulab-bsp

• Set a CompuLab machine:

export MACHINE=ucm-imx8m-plus

Initialize repo manifests

• NXP

repo init -u git://source.codeaurora.org/external/imx/imx-manifest.git -b imx-linux-zeus -m imx-5.4.70-2.3.0.xml
repo sync

• CompuLab

mkdir -p .repo/local_manifests
cd .repo/local_manifests
wget https://raw.githubusercontent.com/compulab-yokneam/meta-bsp-imx8mp/devel/scripts/meta-bsp-imx8mp.xml
cd -

• Sync Them all

repo sync
cd .repo/local_manifests
ln -sf ../../sources/meta-bsp-imx8mp/scripts/meta-bsp-imx8mp.xml .
cd -

Setup build environment

• Initialize the build environment:

source sources/meta-bsp-imx8mp/tools/setup-env -b build-${MACHINE}

• Building the image:

bitbake -k imx-image-full

Deployment

Create a bootable sd card

• Goto the tmp/deploy/images/${MACHINE} directory:

cd tmp/deploy/images/${MACHINE}

• Deploy the image:

sudo bmaptool copy imx-image-full-ucm-imx8m-plus.wic.bz2 --bmap imx-image-full-ucm-imx8m-plus.wic.bmap /dev/sdX
